Description

General part information

THVD2442 Series

THVD2412 and THVD2442 are ±70V fault-protected, full-duplex, RS-422/RS-485 transceivers operating on a single 3V to 5.5V supply. Bus interface pins are protected against overvoltage conditions during all modes of operation ensuring robust communication in rugged industrial environments.

These devices feature integrated IEC ESD protection, eliminating the need for external system-level protection components. Extended ±25V input common-mode range ensures reliable data communication over longer cable run lengths and/or in the presence of large ground loop voltages. Enhanced 250mV receiver hysteresis provides high noise rejection. In addition, the receiver fail-safe feature provides a logic high when the bus inputs are open or shorted together.

THVD24x2 devices are available in small and thermally efficient VSON packages for space-constrained applications. These devices are characterized over ambient temperature from –40°C to 125°C.
